“…Thus, we can reduce the responses of zootechnical performance, confirming that arginine is the first limiting amino acid in dietary protein. The dilution technique might be suitable to increase the range of arginine levels tested ( Lima et al., 2020 ), using the dilution technique, obtained a 333% difference between arginine levels (0.237% and 1.027%) and confirmed its dietary limitation. The authors found a reduced EP by 50% and they could establish the ideal intake of arginine from the responses of the birds to various arginine levels.…”

“…The efficiency of SID Lys and SID Arg utilization (k) was estimated as the slope of the first-degree linear regression equation: AAdep = a + k × AAti, where AAdep (mg) is the studied AA deposition, a is the intercept, and AAti (mg) is the AA intake discounting maintenance needs reported by [8,9]. Based on the efficiency of utilization estimated, two factorial models (one for Lys and one for Arg) were adjusted to estimate broiler requirements for SID Lys and Arg.…”

“…where AAi is the amino acid intake (mg/bird/day), AAT m is the daily intake of SID Lys for maintenance (45 mg) determined by [8] or the daily intake of SID Arg for maintenance (36 mg) determined by [9], k is the efficiency of Lys or Arg utilization, and AATD is the daily amino acid deposition in the body (mg). The daily amino acid deposition was estimated from BWG (body weight gain) according to the linear regression equation:…”

“…Although more appropriate, the decision of applying a factorial approach to predict broiler AA requirements has three main concerns, which include the knowledge of daily growth rates, the amounts of post-absorbed AA partitioned to meet maintenance requirements, and the efficiency at which birds utilize AA for growth. Whereas considerable efforts have been put forwards describing broiler genotypes [6] and estimating maintenance requirements for essential AAs [7][8][9][10][11], little and controversial information regarding the efficiency of AA utilization are available in the literature. The efficiency of utilization of a given AA may be understood as the dietary fraction of such AA, which, after consumed and post-absorbed, is retained in bodily proteins.…”

Six assays were conducted to investigate male and female broiler responses to standardized ileal digestible (SID) lysine (Lys) and arginine (Arg). Response data were modeled to estimate the efficiency of utilization (k) of both amino acids and adjust factorial models to predict bird intake for SID Lys and SID Arg. In each assay, 1280 Cobb 500® broilers (640 male and 640 female) were randomly assigned to one of sixteen dietary treatments with four replicates of 20 birds. Dietary treatments consisted of crescent levels of SID Lys or SID Arg based on the dilution technique. The values of k determined for each phase (1- to 14-, 15- to 28-, and 29- to 42-d-old) and sex were contrasted using linear regression with groups (sex and phase). The estimated efficiencies were 0.79 for Lys and 0.62 for Arg, which were unaffected by phase or sex. Factorial models based on body weight and weight gain (M1) and on body and feather protein weight and deposition (M2) were applied to estimate the SID Lys and Arg intake for growth. The amino acid intake based on M2 had a lower error of prediction. Broiler chickens require 94.9 and 92.9 mg/d of SID Lys and SID Arg to deposit 1 g of body protein.

Arginine is a functional amino acid essential for various physiological processes in poultry. The dietary essentiality of arginine in poultry stems from the absence of the enzyme carbamoyl phosphate synthase-I. The specific requirement for arginine in poultry varies based on several factors, such as age, dietary factors, and physiological status. Additionally, arginine absorption and utilization are also influenced by the presence of antagonists. However, dietary interventions can mitigate the effect of these factors affecting arginine utilization. In poultry, arginine is utilized by four enzymes, namely, inducible nitric oxide synthase arginase, arginine decarboxylase and arginine: glycine amidinotransferase (AGAT). The intermediates and products of arginine metabolism by these enzymes mediate the different physiological functions of arginine in poultry. The most studied function of arginine in humans, as well as poultry, is its role in immune response. Arginine exerts immunomodulatory functions primarily through the metabolites nitric oxide (NO), ornithine, citrulline, and polyamines, which take part in inflammation or the resolution of inflammation. These properties of arginine and arginine metabolites potentiate its use as a nutraceutical to prevent the incidence of enteric diseases in poultry. Furthermore, arginine is utilized by the poultry gut microbiota, the metabolites of which might have important implications for gut microbial composition, immune regulation, metabolism, and overall host health. This comprehensive review provides insights into the multifaceted roles of arginine and arginine metabolites in poultry nutrition and wellbeing, with particular emphasis on the potential of arginine in immune regulation and microbial homeostasis in poultry.
